[PATCH v9 37/38] phy: rockchip: usbdp: Re-init PHY on mux change

From: Sebastian Reichel <hidden>
Date: 2026-07-01 23:35:58
Also in: linux-devicetree, linux-phy, linux-rockchip, linux-usb, lkml
Subsystem: arm/rockchip soc support, generic phy framework, the rest · Maintainers: Heiko Stuebner, Vinod Koul, Linus Torvalds

Ensure that the right part of the PHY are powered up when the
mode changes. This ensures the PHY is re-initialized in the
following two scenarios, which are currently broken:

 - cable orientation changes without DP being involved
 - switching from DP-only into a mode with USB support

Fixes: 2f70bbddeb45 ("phy: rockchip: add usbdp combo phy driver")
